Serial No. 459,482.

Inis invention relates generally .to winding mechanism, especially of the character like,`v the thread-like material issues from a spinnerette Immersed in a bath, and the thus newly-formed or green thread-like material passes then directly to a winding mechamsm consisting essentially of a thread-guide and a rotatable spool, said elements having a transverse movement one with relation to the other so that the thread-like .material is Wound crosswise into a number of superposed series of convolutions first in one direction and then in the other.. The wound material'is subjected to a washing or dyeing 'process by drawing liquid through the convolutions of material and into the interior of the spool. For this reason it is now the custom, as disclosed in my application Ser. No. filed July 13, 1929, to so wind the materlal on the spool that the convolutions' are. slack whereby numerous interstices are formed that facilitate the penetration, by the liquid, of the wound material and shortens the length of time necessary to complete the washing or dyeing process. Such slack also has the advantage that, when the wound material subsequently is subjected toI finishing or drying, the shrinkage thereof willv not place unequal strains on different portions of the material, which unequal strains wound tend to result in a length of material of nonuniform character being produced.

The main object and feature of this invention is to produce a simple and inexpensive mechanism whereby the newl -formed or green thread-like material may e wound into convolutions having slack which, if desired, may be of a highlyirregular character.

In the accompanyingdrawings the invention is disclosed in a concrete and preferred form in which Fig. -1 is a top plan view of Winding mechanism embodying the invention;

Fig. `2 is a vlew in side elevation of the parts disclosed in Fig. 1 with the reciprocatory Ineilxber shown in the middle of-its stroke;

Fig. 3 is a View similar to Fig. 2, but -less l complete, showing the reciprocatory member at one end of its stroke; and Figs. 4 to 7 inclusive are diagrams showing some typical slackformation in the wound thread-like material.

1 indicates a thread-guide and 2 is a rotatable spool mounted on shaft 3 receiving motion from shaft 4 by means of gears 5. Suitable means are provided to effect a relative traverse movement of the guide and spool one with respect to the other. In the present instance, the thread-guide is reciprocated with respect to the spool so as to lay the thread-like material in superposed layers first in one direction and thenin the other as is well understood. In the form of the invention shown, 6 indicates a reciprocatory member sliding on upper and lower guides 7, said member 6 carry thread-guide 1. 8 indicates a rotatable member'carrying a mutilated gear 9 that meshes alternately with upper and lower rack 10 and 11 of member 6. Associated with the reciprocatory and rotatable members is'a cam and roll connection to com,- plete, reverse and initiate the stroke of the reciprocatory member. 'As here shown cams 12 and 13 are mo'unted on member 6 and roll]v or pin 14 is carried on an arm 15 of member 8 or gear 9. Assuming the parts to bein the position shown in F ig. 2 and member `8` to be rotating clockwise, it will be seen that mem? ber 6 will be moved to the left in the figure and that eventually the mutilated gear will disengage rack 11. At about the time this occurs, roll 14 will have engaged cam 13 and will continue the movement of member 6 until the position of the parts shown in Fig. 3 is reached when the cam and roll will reverse the stroke and initiate the movementk of memberv 6in the opposite direction, and, at about the time roll 14 disengagescam 13,

gear 9 will engage rack 10 and continue the movement until roll 14 engages cam 12. VIt is, however, desired to lay the thread on the spool with a considerable slack and the following expedients are therefore resorted to.

Rotatable member Sis provided with a ratchet 15 which is driven by a pawl 16 mounted on crank 17. Crank 17 is rotated continuously by any suitable means such as sprocket 18 and chain 19 reaching from sprocket 20 on shaft 21. In this fashion member 8 is given an intermittent movement and member 6 is given its traverse movement in the form of a series of intermittent steps first in the other direction.l In addition the thread by rocking said pivot by means y The bearing,

` ter 22, and that, in the present instance, this oscillation is continuous, and that the traverse of member 6 is caused by a series of intermittent steps. The lay of the thread Will, of course, vary with the gear ratio of the parts but in Figs. 4 to 7 inclusive are shown some typical lays vof the thread. In these diagrams the length of line a represents one revolution of the spoolv and b is the thread. The sharp deflection c indicates the result of an intermittent step of ymember 6 and the tilated wavy connecting lines olindicate the effect 0f the oscillation of the thread guide. In this example therefore, there is a plurality` of intermittent steps and a plurality of oscillations during a single revolution of the spool. In Fig. 5 there is shown the eil'ect of a plurality of intermittent steps at c and of a single oscillation of the thread-guide at d. In Fig.

6, the effect of a single .intermittent step is shown at| c and of a single oscillation at d. In Fig. 7, the effect of a single intermittent step is shown at c and a plurality of oscillations-is shown at d.
